Behavioral Breeding

Saguinus Nigers care for all of the young. All adult Black Handed Tamarin act as parental figures for raising the young. This effort is included by members of the group that are non-reproductive. Caring for infants is a group effort and may be carried by any adult member of the particular group. Group members coordinate and work together to find sufficient food items for infants and juveniles. Unlike many primate groups that give juveniles little amounts of food, the juveniles of this species have a cooperative breeding system that shares substantial portions of food to the juveniles. When there is a substantial amount of members in one group of Saguinus Niger, the breeding male often spends a substantially less amount of time attending to their own young because of the universal group effort. If there are multiple females reproducing in a certain group, possible scenarios for this are either the superior female is allowing breeding when there is a steady flow of food, or the dominant female is close to the end of her reproductive cycle. Daughters of the same group bred in tend to not ovulate. As soon as the female becomes sexually mature, there are two options; either find another group to reproduce in or stay in the natal group which they were raised. If the female stays in the same group, she can either someday become the dominant female, or cease to ovulate. Becoming the dominant female occurs by replacing her own mother's position, as well as competing for the role with other siblings. Subordinate members of a certain group do not engage in sexual reproduction. During reproduction, the Saguinus Niger, just like all of the Callitrichids, usually produce fraternal twins. With that said they're are variation, and can actually produce litters of 2-4 infants. Triplets and quadruplets usually only occur in captivity. During Birth, the litters of Saguinus Niger account for 15-25 percent of an adult Tamarin. Saguinus Niger mates in a number of variations: Monogamy, polygyny, polyandry, polygynandy. Sexual reproduction occurs within the group; each group contains anywhere around 2-20 members.The growth of the Saguinus Niger as well as other Tamarin is very rapid. It only takes a time period of five months for the Saguinus Niger to become independent. The females of the Saguinus Niger may begin their ovulation cycle in as little as 12-17 months. Males have the ability to create sperm around the age of 13-18 months. Between the two, sexual reproduction starts to occur within a 15-25 month period
